To use: 1) Start with copy of qgsoptionsdialog_template.ui and build options/properties dialog. 2) In source file for dialog, inherit this class instead of QDialog, then in constructor: ... setupUi( this ); // set up .ui file objects initOptionsBase( false ); // set up this class to use .ui objects, optionally restoring base ui ... restoreOptionsBaseUi(); // restore the base ui with initOptionsBase or use this later on
